Kirui, Kiplagat fail to defend Chicago Marathon titles

Dibaba in April this year run 2:17:56 to finish second at the London Marathon, she was beaten by record-breaking Kenyan competitor Mary Keitany who finished the race in 2:17:01.

The Chicago Marathon is a long-standing tradition in the IL city where runners across the United States and the world gather to run through 29 neighborhoods and reach the finish line in Grant Park. Kenyan Abel Kirui came in second, 28 seconds behind Rupp.

"It's just incredible", Rupp said.

The women's race was won by Ethiopian Tirunesh Dibaba in 2:18:31. "I worked very hard for this".

Kenya's Dennis Kimetto, world record holder from his 2014 Berlin Marathon triumph in 2:02:57 and the 2013 Chicago champion, led at the halfway mark in 1:05:49 but began limping soon after and by 25km was off the pace for good.

The last American to win the men's race was Moroccan-born Khalid Khannouchi in 2002. I really wanted to wait.

Dibaba, 32, is a two-time 5,000m world champion and three-time 10,000m world champion. He won his debut at the 2016 U.S. Olympic Marathon Trials before winning a bronze medal at the Olympics in Rio de Janeiro.

Rupp was second at the Boston Marathon. His win on Sunday is the first by an American man at the World Marathon Majors since Meb Keflezighi won the 2014 Boston Marathon.
